What's in the Box

Product Description

These Stop Tech Mustang brake rotors are sold as a pair and offer long lasting and better stopping power over factory Mustang brake rotors.

Mustang Stop Tech brake rotors are finished in a durable black e-coat on the hat, edges and internal vanes to prevent corrosion. The braking surfaces are left in a bare iron finish to improve brake pad bed-in.

Stop Tech rotors are a direct replacement for your factory Mustang rotors. This Mustang application features our Power Alloy metallurgy with increased Molybdenum content for maximum thermal resistance. For best results, follow the "Brake Pad Bed-In" instructions included with every shipment. Brake caliper service or rebuild is recommended for Mustangs with higher mileage.

Excessive heat can cause resins in your Mustang brake pad to vaporize or "outgas." As the brake pad wears, the used friction material turns into a fine dust. This boundary layer of heat, gas and dust builds up between the pad and rotor surfaces and inhibits performance. Here's where Stop Tech's Mustang slotted brake rotors make a big difference.

Stop Tech's exclusive Vac-U-Slots are machined into the rotor and help evacuate gasses and dust, shed heat, and keep the brake pad surface clean. And in wet, raining conditions, our Vac-U-Slot helps push water off the braking surface for better stopping power.

The Vac-U-Slot also serves as a visual wear indicator. The slot is machined to the rotor's minimum thickness where it crosses the outside edge. If you cannot see the slot along the outside edge, the rotor has worn down to its discard depth.

A combination of Hawk® high performance brake pads and StopTech slotted rotors will deliver superior, reliable braking for virtually all automotive, truck and SUV applications, even under hard driving and severe duty conditions.

What length studs are these will they allow spacers?Asked by Jordan W.from Joshua | October 14, 2014 | Comment00

Best Answer:From the face of the rotor to the end of the lug stud is 1.28". The actual threaded area is 1". I would not use more than a 1/8" spacer on stock style studs. I'm not a big fan of spacers anyway. But if you do have to run them I always recommend swapping to hardened studs.Answered by Jonathan M.from Hewitt | October 14, 2014 | Comment00

I have a 79 fox body. Will these rotors swap over easily or is there a NEED to swap the spindles too. I would rather NOT do a spindle swap. If I HAVE to. Will 83 spindles be a direct bolt on?Asked by Lucas M.from Spokane | November 16, 2014 | Comment00

Best Answer:These rotors are designed to fit the 87-93 V8 Spindles which are built differently that the earlier 79-86 spindles they are "beefier" units that have a larger diameter spindle shaft.. All 79-86 Mustangs except SVO had the smaller 4 cylinder spindles and brakes whether they were V8 or not. The 87-93 versions are the easiest upgrade available for all 79-96 Mustangs "excluding SVO models" Answered by Scott G.from hewitt | November 17, 2014 | Comment00

I bought this rotor in combination with the Hawk ceramic brake pads that come in the yellow box. Let me say, holy cow! Fresh out of the box, the rotors were already cut and turned, which I wasn't expecting. With no complications, I threw them right onto the car, (and painted my calipers while I was at it.) After the bed-in period, I started putting them to the test, doing some panic stops from varying speeds. I definitely noticed a dramatic improvement over stock! I'd roughly estimate around a 30% braking performance increase, provided I was running some worn-out stock pads and rotors. I would highly recommend these and the ceramic pads, especially as a replacement for worn stock parts. You will notice the difference!

Yes, I would recommend this item to a friend!

These rotors have stayed true(no warping or pulsation) and stop well for stock type brakes with wagner pads. Have used them for one year and I am still pleased with them.

Great rotors, well constructed. Still had to turn them down a little to really get them trued. With a set of good pads, these rotors are worth their price.

Testimonial: Best Customer Service EVER !!

Had a problem with an order/quality issue. I put up a review stating so, and was contacted by Mike Linley, who was soooo nice and sooo professional, I almost felt bad about my review !! I felt the review was necessary because of bad welds/paint. Mike explained that they had a particular issue with that supplier and they had changed suppliers because of it. I must have mistakenly got an old set. (upper/lower Control arms-Foxbody). Mike asked a few questions, and was Sending me an updated replacement set while we were on the phone.!!! This is what I wish all Vendors would do; no arguments, no blame, no B.S. !! This is why LateModel stands out as an upstanding company, and backs up their products with AWESOME Customer service. Very rare in this day and age, and because of this I will be a customer for life, and will spread the good word ! Great to know some honest and Classy companies still operate in the good ol' USA. Thanks LateModel, and Thanks Mike !!! I look forward to seeing the New LCA'S and will review them too...You guys did the right thing and should and I'm overly impressed!
